OIL SPILLRESPONSE TECHNOLOGY

PU-FF is a patented oleophilic, hydrophobic open-cell flexible polyurethane foam with oleophilic and hydrophobic properties, with density of about 30 kg/m3.
This innovative material, more than 95% hydrophobic, can absorb about 30 times its own weight of various kinds of hydrocarbons (including 10w40 oil, light and heavy fuel oils and crude oils of various API gravities).
Tests have revealed that oil retention capacity is directly proportional to the viscosity of the oil. The material saturates at an extremely fast rate (a few minutes).
PUFF can be reused about 100 times with the aid of a mechanical wringing process performed using special machinery engineered and built by Test1, which allows recovery of about 2 tonnes of oils uncontaminated by water using only about 1 kg of product. The wringing process, even if performed manually and without the use of the dedicated machinery engineered by Test 1, almost completely restores the initial properties of PU-FF, providing oil holding capacity that remains constant whilst the number of cycles increases.

If the clean-up operation takes place in adverse weather conditions, its strong resistance to oil desorption and ability to float (even when saturated with oil) mean that PU-FF can be left in the water even for lengthy periods of time, allowing the foam recovery operations to be performed in safety when favourable weather conditions are restored.
At the end of its life cycle, it can be recycled by means of a regeneration process that avoids landfill disposal or combustion.
The product is not harmful to the marine fauna or flora and is safe for human health. The invention is patented and is registered on the official list of absorbent products kept by the Italian Ministry of the Environment and Environmental Protection, as per the Decree published in Official Gazette no. 114 of 19 May 2009 and subsequent measures.

1KG of product adsorbs more than  2Tons of oil.

SEVERAL SPILLED PRODUCTSONE SOLE SOLUTION

PU-FF’s effectiveness has been tested on various types of oils and hydrocarbons in variable water salinity and temperature conditions. The material’s absorption capacity improves in direct proportion to the increase in viscosity of the product spilt. Absorbency of about 35 times the weight of the polyurethane itself is recorded in the case of crude oil and 10W40 oil. Using diesel fuel and naphtha, absorption capacity of about 23 g/g is recorded. Absorption levels are lower for volatile hydrocarbons such as kerosene.
Tests with crude oil were performed using products with various API degrees: Green Canyon 254 and C-1564.
Tests were performed with a sample of PU-FF previously mechanically saturated with water. In spite of a longer absorption time (because the oil molecules take longer to substitute the water molecules inside the polyurethane), absorption performances in terms of g/g were maintained.
To conclude, the salinity and temperature of the water do not visibly affect PU-FF’s performances
